1. MARK DOOR

Place template on high edge of door bevel,

suggested height 38” (965 mm) from floor. On

door edge, mark centers of 1” (25.4 mm) holes

for both top latch and bottom latch. Check

backset of the lock you are installing, either

2-3/8” or 2-3/4” (60 mm or 70 mm). On door

face, mark centers of 2-1/8” (54 mm) holes for

top and deadbolt bottom leverset. NOTE: Be

sure to use correct backset size.

2. DRILL HOLES

Drill 2-1/8” (54 mm) hole for top

deadbolt and 2-1/8” (54 mm) hole for

bottom leverset through door face. Drill

holes from both sides of door face to

prevent splitting. Drill two 1” (25.4 mm)

holes through centers of door edge.

3. INSTALL LATCHES

A. Insert latch in holes. Latch faces must be parallel

to door face. Mark latch face outline on door edge and

remove latches. Chisel 5/32” (4 mm) deep or until

latch faces are flush with door edge. Insert latches and

tighten #8 screws securely.

B. Latch faces should be vertically aligned.

C. Face plate will be flush with door edge after

tightening the screws.

4. INSTALL STRIKES

A. Close door until latchbolts

touch jamb to locate strike on

jamb and center line of strike.

Open door and extend line from

mark to door stop. Measure one

half of door thickness plus 1/8”

(3.2 mm) from stop and vertically

mark center line for strike.

B To prep the deadbolt strike, drill

two (2) 1” (25.4 mm) diameter holes 1”

deep in door jamb 5/16” (8 mm) above

and 5/16” (8 mm) below the horizontal

center line. To prep the T-strike, drill

two (2) 1” (25.4 mm) diameter holes

5/8” (15.9 mm) deep in door jamb

3/16” (4.7 mm) above and 3/16” (4.7

mm) below the horizontal center line.

C. Match screw holes on the deadbolt strike with vertical

center line on jamb. Mark the outline of the strike and chisel

that area 1/4” (6.4 mm) deep for flush fit of dust box, wood

frame reinforcer, and strike. Tighten dust box and wood frame

reinforcer to frame using 3” wood screws. Insert strike and

tighten to frame using #8 screws. Next, mark outline of T-strike

on jamb. Mortise that area 3/32” (2.4 mm). Tighten T-strike to

the frame using two (2) #8 screws. NOTE: Bottom strike has an

adjustable tab that can be bent in or out to eliminate loose fit

between door and door stop.

end of the rose. Rotate the rose in or

out to align the end of the sleeve with

the tick mark that corresponds to the

proper door thickness.

7. INSTALL LOCK ASSEMBLY

deadbolt and cylindrical lock, make sure that the

latchbolt of the upper deadbolt is not projecting prior

to inserting the tail piece into the latch hole

horizontally.

guard. Be sure to insert tail piece horizontally

through latch hole.

D. Install inside liner, tighten installation screw of
